I have a list with simple_list_item_multiple_choice layout. The list is all in white and my background is also white and hence it is not visible. How do I change the color for that?

To give the user of my app an indication which field currently has the focus I am trying to change the background color of some of my fields depending on the current state, however, I am having troubles understanding Androids Color State List Resources:
There is this example at the bottom of http://developer.android.com/guide/topics/resources/color-list-resource.html. If I try exactly the same, i.e. if I want to adapt the textColor , things do work. However, if I try an only slightly different thing, namely to adapt the background color, things do not work and I don't understand why? Why is this so inconsistent?
To make it simpler to understand what I am trying to do, I append my misc. .xml files:
The AndroidManifest.xml file:
CODE:.........
If I run this as shown here, it works, i.e. I get a button whose text color changes depending on whether the button is focuses, pressed, etc.
If I uncomment the lower button, where I just flipped the attribute values for textColor and background I get an exception, stating
... <item> tag requires a 'drawable' attribute or child tag defining a drawable
What the heck am I missing here? Why is that color state list acceptable as a text color but not as a background color? How does one specify a view's background color depending on the view's state?
I'm trying to create a multiple selection list where the selection is represented graphically rather than with checkboxes.My list has checkboxes, but I want them to serve a different purpose. I'm using a cursor to hold my data and created a custom view binder for the SimpleCursorAdapter. I did this for the checkboxes and general flexibility.So far I haven't even been able to show one line as being selected. I've enabled multiple selection on the list and denied the children of the list item focusability. I've tried manually changing background color with the position fed in through the list item click listener. But the wrong items get changed and they don't even change to the right color. I've enabled touch focusability with no improvement either.Ideally, I'd like the trackball highlight focus bar to appear in multiple places. But I don't think this is possible unless you use the drawable directly. But I don't know how to find or apply it. My next idea was to have a slim view bar that changes color. But I had the same problem with the wrong item being selected so I never finished trying to guess the index position to see if this would work. My most recent idea is to completely swap out the view for another one if it's selected. But I have no idea how to do this either. I'm thinking of using an array list to store the _id s of the items that need a different view to get around the wierd selection problem. I'm also thinking of passing in the ID field as my from and the selection view as the to for my adapter. Then I'd intercept it with my binder and change the view accordingly. But once again, I'm not sure how to do this successfuly.
View 7 Replies View RelatedI am trying to change the text color of the spinner list items individually. I would like to be able to color the top three texts black and then the bottom four grey. This way the last items look disabled, but I still want to be able to capture the event when they are chosen. I haven't been able to find any documentation on how to do that. Alternatively I would like to disable som list items, but still be able to capture the event when they are chosen.

I've tried to assign that selector programatically and using the xml, but the app crashes. Am i doing something wrong?
